More and more people are beginning to switch to LED Lighting as their primary source of illumination. This LED Monkey guide tells you how to recognise a GU10 fitting, so you'll be able to make a more informed decision about which type is the best to adopt.

What IS a GU10?

The GU10 is, without a doubt, the type of spotlight fitting that’s most commonly found in most homes today. It’s ideally suited to locations in which a bright, directional light is required, like kitchen areas, hallways, bathrooms and work spaces. It has the classic spotlight shape, featuring a slender base that widens into a flat or very slightly domed aperture.

The name “GU10” refers to the type of fitting this spotlight bulb has.

You’ll see from the picture on the left that it features two short, stumpy pins protruding from the base of the bulb, 10mm apart from the centre of each.

Similar to the ever-popular Bayonet Cap (B15 & B22), the GU10 utilises a ‘push-and-twist’ method of attachment and detachment, however the two types of bulb are not interchangeable.

It’s important when purchasing, that you don’t confuse a GU10 spotlight bulb with an MR16 spotlight bulb (pictured, right). At first, they may seem almost identical, but on closer inspection you’ll notice a distinct difference in the pins.

As you can see from the photo, the MR16’s are literally pins – thin and needle-like in comparison with the GU10’s two chubby pins.

EU Law Bans Halogens – Enter LEDs

A 2016 EU edict banned the production and sale of halogen GU10 bulbs across the Union, and we’re going to see that enforced here in the UK in 2018.

Fortunately, you don’t have to worry about this being the end of the line for all your spotlight fittings, because LED GU10 spotlights will directly replace them.

LED GU10 spotlight bulbs are the ideal choice to replace your old halogens. For one thing, they’re designed to resemble halogen bulbs, so their aesthetics shouldn’t put anyone off.

Indeed, they boast the classic GU10 shape that we’ve all come to know and love, being manufactured from 100% recyclable materials that won’t cause harm to the environment.

Ultra-Cost-Effective LED GU10s

Unbelievably energy-efficient, LED GU10s consume around 90% less electricity than conventional halogen GU10 spotlight bulbs. Indeed, a 5-watt LED GU10 can generate the same number of Lumens (Lumens = Light Output) as a 50-watt halogen model.

This reduced energy consumption isn’t just great for the environment, it’s great for your pocket too, as your electricity bills will fall quite significantly when you make the switch.

With the continued development and improvements to their quality, the life-expectancy of most high-quality LED GU10s has now risen to around 50,000 hours, as opposed to the 8,000 you could expect a halogen to achieve.

To put this in real terms, if you had your LED GU10 switched on for 4 hours every day, you’d be over 30 years older by the time it needed replacing!

LED Colour Temperatures

While conventional halogen GU10s were only capable of producing a bright, white light, LED GU10s are available in 3 distinct colour temperatures.

As you'll see from the image below, this choice will make it easy for you to imbue each of your rooms with a different lighting ambience according to its particular function.

Like physical temperatures, LED colour temperatures are measured against the Kelvin Scale. Take a look at the chart below, to see which LED colour temperature is best suited to which environment.
